Accurate and easy to use, the HI9810462 HALO2 Wireless Refillable pH Tester is ideal for laboratory pH measurements in samples that would be a challenge for standard design pH electrodes. This HALO2 can be used as a stand-alone pH tester or can be connected to a smart device with the Hanna Lab App.

The open-source Bluetooth® protocol allows easy integration with the Hanna Lab App and current Laboratory Information Management System (LIMS). This HALO2 Wireless pH Tester is GLP compliant.
The housing of the pH Tester is rated IP65 meaning it has a high level of protection against particles and dust, and protection against the ingress of water from jets. This makes it ideal for outdoor use.
The compact size makes the pH Tester ideal for on-the-go testing. A large LCD display provides at-a-glance readings from any angle and single button operation streamlines the testing process for any user.

General Purpose (GP) glass provides the best response over the entire pH range and can be used for a wide range of applications.
The HALO2 Lab pH Tester (HI9810462) features a built-in temperature sensor for temperature measurement and compensation.
The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions due to its large surface area. Other tip shapes include conic for penetration and flat tip for surface measurements.

Your HALO2 pH Tester comes with cleaning solution that has been engineered to keep your electrode free from grease and debris. This concentrated combination of detergents cleans your meter quickly and effectively so that your meter stays in optimum condition.
HALO2 can be placed right into our calibration buffer sachets for easy calibration. Using a Hanna calibration sachet ensures your buffer is always fresh.
Proper storage of your electrode will ensure reliable measurements and a long electrode life. Our storage solution is specially formulated to keep the pH glass hydrated while minimizing organic growth.
